Question

If the A and B loci are 20 mu apart.

a) They are on the same chromosome.
b) They are on different chromosomes.
c) They are closely linked.
d) They are unlinked.

Answer 1

Linked genes are located on the same chromosome and are inherited together, while unlinked genes are located on different chromosomes and show independent assortment.

Step-by-step explanation:

When two genes are located close together on the same chromosome, they are considered linked genes. These genes tend to be inherited together, although there is a possibility of separation through crossing-over during meiosis. If the genes are located on different chromosomes, they are considered unlinked, and independent assortment occurs during meiosis.
